SPECIFICATION forming part of Letters Patent N o. 666,554, dated January 22, 1901.

Application filed May 12, 1899. Serial No. 716,538. (No model.)

To CML whom, t may concer-n.-

Bc it known that we, EDWARD E. PETTEE and JOHN J. MCCUTOHAN, citizens of the United States, residing at New York, in the 5 county of New York and State-of New York,

have invented certain new and useful Improvements in Suspension of Engines Upon Vehicles; and we do hereby declare the following to be a full, clear, and exact descripio tion of the invention, such as will enable others skilled in the art to which it appertans 1.o make and use the same.

Our invention relates to improvements in the suspension of explosive or other recipro- [5 eating engines upon vehicles, and has for its object to so mount or locate the engine thereon that the vibrations caused by the reciprocat-ion shall not be transmitted to the body of the vehicle.

In carrying out our invention we suspend the engine upon springs that bear upon the running-gear of the vehicle, while the body of the vehicle rests upon other springs which have no connection with those supporting the z5 engine. In this manner the vibration of the engine is taken up by the resiliency of its supporting-springs and no vibration is transmitted to the body of the vehicle.

In the accompanying drawings, Figure l 3o represents in sectional elevation the application to a vehicle of one forni or modification of the invention, the shaft of the engine being geared directly to the wheel-h ubs. Fig. 2 represents a top plan view thereof. Fig. 3

35 represents a rear elevation thereof.

5, and (i represent similar views of another forni or modification thereof, the engine-shaft being geared indirectly to the vehicle-hubs through the intermediacy of bevel-gearing 4o and asecondary transmitting-shaft; and Figs. 7, S, and 9 represent similar views of another form or modification wherein independent motors are located upon the Vehicle-hubs and are actuated by compressed air supplied from 45 a combined engine and air-compressor.

Similar letters of reference indicate similar parts throughout the several views.

In the form shown in Figs. l, 2, and 3, A represents any ordinary explosive or recipro- Figs. 4,.

eating engine having a shaft Gr, operated by 5o its piston. To the shaft G are attached the ily-wheel M and pinions I, which mesh with the gear-wheels H, rigidly attached to the hubsdof the vehicle-wheels. The shaft G is sipported'uponthe vehicle-axle K by the 55 bearings J, which insures a proper meshing of thegear-whecls. The engine A is formed with a bracket L, through which the axle K passes, and which forms a bearing for the engine upon the axle, thereby securing a per- 6o fect alinement of the shaft G in all possible positions. In additionA to the supportingbracket L we suspend the engine upon the cross-springs B and C, which in turn are supported by the coil-springs D and E, that bear 65 upon the running-gear F. The plate N is secured to the base of the engine and also to the springs B and O, forming a seat for the engine. As the engine is upright, it will be seen that the blow caused by the operation of 7o the engine is downward and is received by the springs, which take up the vibratory effect and prevent transmission of the jar of the engine to the body of the vehicle.

In the form shown in Figs. 4, 5, and 6, A' 75 represents, as before, any ordinary explosive or reciprocating engine having a shaft G', operated by its piston. To the shaft G' are attached the fly-wheel M' and the bevel-pinion R, which meshes with the bevel gear-Wheel 8o R', attached to the shaft S. The shaft S is supported by the bearings L', attached to the engine A', and by the bearings J', attached to the vehicle-axle K'. At the ends of the shaft S are secured the pinions I', meshing 85 with the gear-wheels H', which are rigidly attached to the hubs of the vehicle. The bearings J' beingsdrigidly attached to the axle K' insure a perfect alinernent of the shaft G' and a positive meshing of the gear-wheels I' and 9o H'. -To the axle is secured the runninggear or frame F' of the vehicle, and from this frame are suspended the cross flat leaf-springs B' and O'. These springs rest upon the coilsprings D' and E', which encompass hangers 95 or Suspenders attached to the running-gear, as shown in Fig. 4. Upon the fiat leaf-springs is placed the engine A' in an upright position and attached thereto by its base N/ in such a manner that the jar of the engine is taken up by these springs.

In Figs. 7, 8, and 9, A2 represents an explosive or reciprocating engine in combination with an air-compressor for compressing air to operate the motors T, which are attached to the hubs of the vehicle. flexible connections from the compressors to the motors. K2 is the axle to which the running-gear F2 is attached, and B2 C2 are crosssprings supporting the engine in an upright position resting upon the coil-springs D2 E2, which are supported by hanger-rods,as before, from the running-gear. A suitable form of combined explosive engine and air coinpressor for use in this connection is illustrated, for instance, in our prior applications for Letters Patent, Serial Nos. '708,421 and 708,422, filed March 9, 1899.

lt will of course be understood that the vehicle-body is to be supported upon springs independent of those which support the engine.

It ischaracteristic of all of the modiications illustrated that when the engine is in operation the explosions and the movements of its piston will be manifested in the form of a downward and upward thrust and that the consequent jars, shocks, or vibrations will be transmitted to and taken up by the suspending-springs instead of being transmitted to the body of the vehicle.

It is further characteristic of our invention that the engine and Fly-wheel have substantially a central location with respect to the running-gear and that in the form illustrated in Figs. '7, S, and 9 the liy-Wheel rotates in a piane transverse to the tread of the wheels, thereby reducing` the vibratory eect of the revolving ily-wheel to a considerable extent.

In.- the use of an explosive or like reciprocating engine mounted upon the body portion of a vehicle to propel the same great annoyance and inconvenience are caused by such vibrations and throbbings of the engine trans- T denotes Having thus described our invention, what we claim is- 1. In a inotor-vehicle, the combination of p the running-gear' comprising rods or bars joining the front and rear axles, springs supported by said rods or bars, cross-springs spanning the opening between the rods or bars and supported bythe first-named springs, an engine carried bythe cross-springs independent of the vehicle-body, and actuating means between the engine and the vehicle- Wheels.

2. In a motor-Vehicle, the combination of the running-gear comprising rods or bars joining the front and rear axles, springs supported by said rods or bars, cross-springs spanning the opening between the rods or bars and supported by the said first-named springs, a motor carried bythe cross-springs independent of the vehicle-body, and compensating connections between the motor and axle of the vehicle.

3. In a motor-Vehicle, the combination of the running-gear comprising rods or bars joining the front and rear axles, coiled springs supported by said rods or bars, cross-springs spanning the opening between said rods or bars and having their ends supported by said coiled springs, a motor carried by the crosssprings independent of the vehicle-body, and alining connections between the motor and axle of the vehicle.

In testimony whereof We afx our signatures in presence of two witnesses.
